Don't allow the negative height of ListPopupWindow
Symptom:
If an application set a negative height to the popup list,
surfaceflinger is crashed with SIGABRT.
Root cause:
WindowManagerService dose not expect negative
height of ListPopupWindow. If it's negative,
WindowManagerService set the negative value to GraphicBufferAlloc,
but GraphicBufferAlloc handle the value as unsigned int,
then surfaceflinger is crashed with SIGABRT.
Solution:
Setting a negative height is a developer error.
We should throw an IAE from setHeigh(int).
